  17.     I have to write a program that calculates the fractal dimension
  18. by 'walking' around the edge of a scanned micro-organism.  I have input
  19. in the form of x,y coordinates.  
  20.  
  21.     Does anybody have or know of an algorithm that uses the 'caliper
  22. method' to measure the distance?
  23.  
  24.     C++ preferably but C or Pascal will also do.
  25.
